Abstract In order for capital-intensive deepwater prospects to remain at investment grade potential, it is important the industry achieve meaningful improvement in capital efficiency. Achieving this goal will require a multi-faceted strategy in which advanced new technology and digital transformation will play a determining role. This paper will address the optimization of rig operations through deployment of an advanced Remotely Operated Vehicle (ROV) system that leverages precision robotics and automation technologies; reducing total cost of ownership (TCO) through increased rig productivity, operational certainty and overall utilization. Current ROV technology faces several key limitations which contribute to both schedule and cost variation. These inefficiencies are a combination of human skill variance, ROV system limitations and reliability. Advanced ROV systems have been deployed on two deepwater rigs to demonstrate that machine vision and precision robotics technologies will radically improve the predictability and efficiency of operations. Comprehensive metrics addressing safety, budget impact, cost avoidance & reduction, inventory reduction & non price TCO have been developed to capture the efficiencies and identify the net improvement to drilling and completion operations and yield outcome-based performance. An overview of the key deficiencies and limitations of legacy ROV operations will be conveyed, focusing on; i) High dependency on ROV pilot subsea task skills, ii) Worksite efficiency and ROV availability, iii) Restricted tooling capabilities per dive, iv) Rental tooling logistics and cost, v) Equipment reliability at depth, vi) Inefficient tooling changes, and vii) Dive duration and lost time efficiency launch/recovery time. An overview of how the advanced ROV system resolves these issues will be explained. In addition, an explanation of the productivity metrics will be conveyed, supported with data from the active offshore projects. Key conclusions from the data identify that enhanced robotics will achieve the objectives of i) Reducing schedule and cost risks which improve total cost of ownership, ii) Enhancing capability and improved wellsite efficiency, and iii) Increasing subsea data. The performance issues of legacy ROV operations and associated project cost impact is currently not widely recognized by the offshore drilling community. The realized limitations of such ROV operations and lack of useful performance metrics to identify non-productive time will be explained. The progression in robotic design that drives a new era of subsea robotic efficiency will be conveyed with results from offshore operations, combined with robust metrics that enable significant operational value and cost savings to be attained.

Business To Business

Business-to-business firms know that being able to obtain a higher price than competitors and to keep customers happy they must deliver something the customer perceives as value. To support customers to be able and willing to pay this value, a customized, quantified business case needs to be developed to allow the customer to see the payback for whatever investment is being requested versus other alternatives. A previous methodology to do this was to look at the total cost of ownership (TCO) of the proposed purchase over its life. However, too often, TCO became the total cost of acquisition by procurement people (missing the installation, operational and disposal phases, which is often 8 times more important than the landed cost). The next evolution is to look at a more holistic measurement of value that takes into account not only cost savings but all improvements, such as risk reductions, increased revenue and customer satisfaction. Only then can buyers and sellers make decisions on who is creating the best value and what someone should be willing to pay for it. Anyone who can demonstrate and document the greatest value surplus is the one delivering the best value.

Although transit buses have a relatively small impact on greenhouse gas emissions, they have a larger impact on urban air quality, have commercially available electric models, and have historically commercialized clean technologies that enabled deployment in other heavy-duty vehicles. This paper investigates what factors affect transit agencies’ decisions to go beyond electric bus pilots to larger scale deployments, with the goal of identifying strategies to enable an accelerated transition to an electrified fleet. This mixed methods analysis utilized quantitative total cost of ownership analysis and qualitative interviews to study the barriers and drivers of electric bus investment for transit fleets in three case study states: California, Kentucky, and Massachusetts. A total cost of ownership analysis estimated electric buses are already more cost-effective than diesel buses in many agency contexts, but are sensitive to key parameters such as annual mileage, fossil fuel costs, and electricity tariffs and supporting policies that vary widely. Though multiple agencies in California reported planning to fully electrify their fleets, outside California where less supportive policies exist, fewer agencies reported planning to procure additional electric buses, primarily owing to high first cost and undesirable tradeoffs with maintaining transit service levels. Interview respondents also reported other substantial barriers such as oversubscribed grant programs, charging infrastructure costs, electricity costs, and additional operational complexity, suggesting a need for multiple complementary policies to overcome these barriers and ensure agencies can transition to a new technology without affecting transit service.

Realitätsnahe Lebensdauerprognosen sind für eine ganzheitliche, betriebswirtschaftliche Kostenbetrachtung sehr wichtig. Wirtschaft und Forschung bemühen sich seit Langem, die Total Cost of Ownership (TCO) von Werkzeugmaschinen zu berücksichtigen. Eine Umfrage unter Herstellern und Betreibern von Werkzeugmaschinen analysiert Verbreitung, erwartete Potentiale sowie Hemmnisse von TCO-Betrachtungen. Anhand der Anforderungen der Branche wurde ein Modell mit Fokus auf der belastungsabhängigen Beschreibung des Ausfallverhaltens von Maschinen und Anlagen entwickelt, das in bestehende Standards eingebettet werden kann.   A realistic lifetime prediction is highly valued in a holistic economic cost consideration. For years, industry and research have endeavored to consider the Total Cost of Ownership (TCO) of a machine tool. A survey of manufacturers and operators of machine tools analyzes distribution, expected potential and obstacles of TCO. Based on the identified requirements, a model that can be integrated into existing standards has been developed. It focuses on failure behavior of machines and plants, taking stresses into account.

The Impact

Despite the commonly observed trend towards mechanization and automation of operational processes, the potential benefits of wooden pallets as an essential element of the infrastructure of logistic processes are often overlooked in considerations related to sustainable development. Aspects that are mentioned more often include the very idea of the economy itself (circular economy), characteristics of logistics (green), features of the supply chain itself (sustainable) or expectations towards transport (ecological). The authors believe that the idea of total cost of ownership (TCO) in relation to wooden pallets can be a key component of holistic thinking in terms of sustainable development. In a situation where in relation to logistics, reasonable expectations for developing sustainable supply chains are made, paying attention to such a common logistic facility, namely a cargo pallet, which is given so little attention in research, is, in the opinion of the authors, absolutely justified. Therefore, the article presents an original approach to the problem of aggregation of all costs that cargo pallets generate in their operational life cycle, using the total cost of ownership (TCO) analysis methodology. The main goal of the article, however, is to show that the total cost of ownership of a pallet (not only owning it) can become an effective tool used to significantly reduce the costs of logistic activity of enterprises (as well as whole supply chains) and support the idea of sustainable development in practice. Using the primary data from questionnaire research, the focus was on considerations that were of identification character (cognitive and explanatory considerations), which are typical for basic research that aims to explain given phenomena. Thus, the presented cognitive process covers two main areas, namely: the general theory of sustainable development and the specificity of wooden pallets as carriers used in goods trading in terms of their total costs of ownership.
